Assuming that str is a correctly initialized String (that does not start with a space), which of the following best describes what the algorithm below does? int index = str. indexOf(" ");
while (index != -1)
{
System. out. print(str. substring(index - 1, index));
str = str. substring(index + 1);
index = str. indexOf(" ");
}

A. Prints the character after each space in str.
B. Prints the character before each space in str.
C. Prints characters from str in an infinite loop.
D. Prints each character in str followed by a space.
E. Prints the number of times a space appears in str.
